Jennifer Garner in Ben Affleck manhood quip

08 October 2014

Jennifer Garner has joked 'Gone Girl' producers must have used a ''wide lens'' to capture her husband Ben Affleck's manhood.

The 42-year-old actress - who has been married to the Hollywood star since 2005 - had a conversion with him over dinner about a scene in which he appears fully naked in the thriller, and quipped the reason the film is tipped to become number one at the box office is because of his penis.

In an interview on 'The Ellen DeGeneres Show', which is due to air today (08.10.14), Jennifer explained: ''He came home and was like, 'Hey, at work today [David] Fincher talked me into walking out of the shower.' And I was like 'Oh, cool. I hope he had on a wide lens.' ''

Jennifer joked she was ''giving something back'' to the world by letting Ben go full frontal in the motion picture.

She added: ''I think you're probably onto something. And to be honest what I have to say is you're welcome.

''I try to consider myself a charitable person. You give me so much and I wanted to give something back to all of you.''

Jennifer's comments come after Ben - who has three children, Violet, eight, Seraphina, five, and Samuel, two, with the brunette beauty - joked his member looks a lot better in 3D screenings of the movie.

He said: ''I think there's some brief nudity in this movie

''Director David [Fincher] said to me from the beginning, 'This is a warts and all movie. It can have no vanity. You have to see the naked underbelly of this character. It's gotta be like in Europe, they just don't give a s**t about any of that stuff and they just play real people'... [So] there is some brief, very brief nudity, I think.

''The penis is in there! It's IMAX penis! You've gotta pay fifteen bucks to see it in 3D ... it's better in 3D.''

The movie sees Ben star as bar owner Nick Dunne whose life is upside down when his wife Amy (Rosamund Pike) goes missing and he becomes the main suspect.

The motion picture is adapted from the novel of the same name by Gillian Flynn and also stars Neil Patrick Harris as Amy's ex-boyfriend and Emily Ratajkowski as Nick's mistress.
